So, these use statements are *outside* a namespace.

That is perfectly fine. However, if you define a namespace and then place your code (expect use declarations) really outside that namespace as in the following example: <?php namespace test{ //inside a namespace } //outside a namespace, not even in the default namespace -> PHP will emit an error require_once 'vendor/autoload.php'; use Foo\Bar; $bar = new Bar(); $bar->doSomethingWithBar(); ?> then PHP will emit an error (which is the correct behaviour). It should also emit an error for the use declaration outside a namespace but this is a different story (should be addressed in PHP 7). I am writing to the standard list since I believe the specification should not cover this "feature"
